Import Cdm Titanium Seamless Tube, Welded Tube — Buy in Bulk from Supplier in China

CDM Titanium Seamless Tube and Welded Tube are precision-engineered products made from commercially pure titanium or Ti-6Al-4V alloy, as indicated by the supplier’s product line. The seamless variant is produced via extrusion and cold drawing, achieving wall thickness tolerances of ±5% and outer diameter tolerances of ±0.1 mm. The welded tubes are manufactured using TIG welding with full penetration and inert gas shielding, ensuring structural integrity without internal seams. These tubes are not coated or plated and retain the natural oxide layer of titanium, which enhances corrosion resistance in chloride and acidic environments.

Typical material grades conform to ASTM B337 and ASTM B861 standards, with seamless tubes commonly available in Grade 2 (CP-Ti) and Grade 5 (Ti-6Al-4V), while welded tubes are generally Grade 2. Standard outer diameters range from 6.35 mm to 152.4 mm, with wall thicknesses between 0.3 mm and 6.35 mm. The tubes are supplied in straight lengths of 3 to 6 meters, though custom cutting is possible. Surface finish is typically pickled and passivated to remove free iron and scale, resulting in a matte gray appearance. These are not polished or bright-finished unless specified.

These tubes are primarily used in heat exchangers, condensers, desalination plants, and aerospace fluid systems where resistance to pitting, crevice corrosion, and stress corrosion cracking is critical. Buyers include manufacturers of chemical processing equipment, marine engineering firms, and OEMs in the medical and aerospace sectors. Trade terms offered include FOB Shanghai, CIF ports worldwide, and payment via T/T or L/C. Minimum order quantities are not stated but are typically negotiated based on tube dimensions and grade. Packaging is in wooden crates with moisture-resistant lining, and each tube is marked with grade, batch number, and ASTM reference.
